This invention relates to haircurlingdevices, and, in particular, to pincurl forming devices.

One object of this invention is to provide a-pin curl forming devicewhich in a simple and effective manner forms a pin curl, holds thepincurl while a so-called bobby-pin is inserted with-its legs-passingabove and below the pin curl, and thenreleases the pin curl, leaving thebobby-pin in a clamping position on the pin curl. K 7

Another object is to provide a pin curl forming device having arotatablerod with a curl holding slot and a slidable guide or curl holder for notonly holding the curl in position after it has been wound around therod, but also for guiding the legs of the bobby-pin Whilethey are beinginserted below and above the curl.

, Another object is toprovide a pin curl forming device of the foregoingcharacter wherein the slider has arms for holding down the pin curlbeing formed and also for guiding the legs. of the hobby pin into theslot in the slider and rod, the arms being spaced apart from one anothercircumferentially a suflicient distance to permit the insertion of thefinger-tips when holding the bobby-pin up to the edge of the guide slot,the circumferential widths of the spaces between the arms being aplurality of times greater than thecircumferential widths of said armsthereby enabling the bobby-pin to be pushed completely into positionwith its legs below and above the pin curl without interference from anyportion of the curl holder.

Another object is to provide a modified pin curl forming device of theforegoing character wherein the curl holder or slider has wings whichare especially well adapted for use with a magazine bobby-pin holder,

, Another object is to provide a pin curl forming device of theforegoing character having a ledge or shoulder thereon adapted to assistthe user in: opening the bobby-pin prior to its insertio below and abovethe pin curl.

Referring to the drawings in detail, Figure I shows 'a pin curlformingdevice, generally designated Ill as'consisting generally of acurl-form,-v ing rod or body ll having a curl holder [2 slidably mountedthereon and a dividing or blocking comb I3 mounted on the upper end .ofthe rod I I. The rod ll is preferably of circular cross-section with oneor more longitudinal grooves [4 extending lengthwise thereof. Extendinginward from the lower end [5 of the rod II are one or more slots l6, twoslots Hi crossing one another at right angles being the preferredarrangement, although a single slot can also be used. The slots l6 attheir upper ends ll have end walls 18 inclined downward and inwardtoward the center I! thereof.

Slidably mounted on the rod H is the tubular sleeve portion 20 of thecurl holder or slider 12, the portion 20 having projections 2| extendinginward into the slots 14 so as to permit longitudinal sliding withoutrotation of the curl holder H. The sleeve portion 20 is provided withguide slots 22 aligned with the slots IS in the rod or body II, thesides 23 of the slots 22 being preferably flared (Figure 2) tofacilitate insertion of the bobby-pin P. The curl holder I2 is alsoprovided witha plurality of arms 25 projecting outward from the sleeveportion 20 and having curved base portions 26 leading inward from thearms 25 to the slots 22 so as to guide the bobby-pin into the slots 26and IS in the event that it strikes to one side or the other of theslots 22. The arms 25 have bottom portions 21 adapted to rest upon thecurl C (Figure 6) and prevent it from slipping or unwinding While thebobby-pin is being inserted. Mounted on the upper end 28 of the rod orbody H is a dividing comb 29. The circumferential widths of the spacesbetween the arms 25 (Figure 2) are a plurality of times thecircumferential widths of the arms 25 themselves, so that the relativelywide spaces between the relatively narrow arms 25 permit the fingers tobe inserted between the arms 25 while inserting a bobby pin, withoutinterference with the arms 25.

The modification, generally designated 30, shown in Figures 7 and 8, hasa body or rod H similar to the rod H of Figures lto (Sinclusive andtherefdre similarly designated'as to its component parts, including thegrooves I4; Slidably mounted on the body I l is a modified curl holderor slider 3|. This consists of a sleeve portion 32 having pins 33inserted therein and projecting I into'the longitudinal grooves M of therod ll Secured to the sleeve portion 32 are the'longi- 4 legs A of thebobby pin P by the converging sides and curved portions 26 of the arms25 (Figure 2) and also by the flared sides 23 of the slots 22. Theseportions serve to guide the ends of the legs A into the slots 22 andthence into the slots IS in the rod ll. Since the arms 25 are spacedapproximately 90 apart and the circumferential widths of the spacesbetween them are a plurality of times the circumferential widths .of thearms 25 (Figure 2),Vtl1e fingertips holding the closed end E of thebobby "pin P can be 'insert'd as far as the slot 22 without interferencefrom the arms "25, thereby permitting the bobby pin P to be fully eralportions 36 of which project outward radially from the sleeve portion32. The curl holder 3| is provided with longitudinal guide slots 31arrangedbetween the longitudinal wing portions Miandgaligned.withtherodslots I6, as'in the form-of-the invention'shown iniFigu'res 1 totinclusive; The ..lateral wing portions 36 have rounded ends t-S and-arespaced apart from one another a sufficient distance to permit thefingersto be inserted between themwhile inserting a bobby-pin. 8 v l Themodification, generally designated. 40, shown. in Figures 9 andlO,likewise employs'the same body or rod l l with its longitudinal groovesI4 and has a curl holderor slider 4i provided with afsleeve portion 42having, as. before, pins 43 projecting into the slots :4.'-to prevent:rotation (Figure .10) Radiatingoutward .fromithe sleeve portion 42 atthe lower-end thereof are wings: 44 having upturned edges 4.5 servingto; guide a bobby pint into a longitudinal slot'fifi similar tothe-longitudinal slots; 22 and'flofFigures 1 and 7 respectively andsimilarly aligned with and guid-' ing'. a bobby pin Pinto the: slot ISin the: lower end; of the .rod H:-..' The modification 'dlzoil' Figures9 and 10 is. especially well adapted for use with a inag'azinebobbylspin holder of: the type described and claimed in myco-pending.applicationSerial No.-l66,883 filed'June 8, 1950.for'MagazinezBobby Pin Holder, now abandoned.

Intheuse of-the form of the invention shown: iii-Figures 1 to 6 inc.,the operator grasps the upper portion o'f -the'rod II with the slider orcurl holder l2 drawn upward to expose the slots F5 and positions thebody I l approximately tangentially to the head H of the-person whose:hair is tobe curled (Figure 5 operator'then uses-the-comb -todivide thehairand s'epa-rate a lock L, the free end of which heorsheinsertsthrough one-'ef'theslots ta rheoperatoe their rolls thelock-hinto a coil by rotating the body or'rod H in his orherfi'ngers;thereby-forming the curl G, Whenthe-lock-Lis fully-wound onthe rod I l toform the curl C, the-'opera tbn'tlien turns the'rod I linto a'p os'iti'orr substantiallyra dial or perpendicular to the head 'Ha-n'd at the same time brings the --lower end t5" into" contact with thescalp in the manner shown} in Fig-ure- 6'3 The operator? then slides the'curl holder or slider 12" downward? into engagement? witlr the curl Cso as to hold the curl firnily against-the head H while the hobbypin P'is inserted.""'l o insert'the bobbypin Pf, the operatbr first ega;rates the" legs A, inserting 'tlie lowerjl'eg againstthe scalpbeneath-the curl G and the upper leg above it (Figure 6); 5 If the'persowhoseriaie s being-curled is forming the cur-l's' herselffwithoutoutside assistance, she is assisted-in-in'serting the "inserted When thehobby pin P has been fully inserted,
